This is a 097-0125R-600 76.2 mm Dia. N-BK7 Protected Silver Plano-Concave Spherical Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a diameter of 76.2 mm and a thickness of 12.7 mm at the edge, making it suitable for various optical applications.
The mirror's base shape is circular, and it features a concave geometry with a radius of curvature (R1) of -600 mm. This curvature results in a focal length (EFL) of -300 mm, which is typical for concave mirrors. The mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transmission range.
The mirror is coated with EKS 0025protsil 4000 on the front side, a protected silver coating that offers high reflectivity across a broad spectrum, including the specified wavelength of 400 nm. The protected silver coating ensures durability and resistance to tarnish, making it an ideal choice for applications requiring high-performance and long-lasting mirrors.
